Re: [Amel Yacht Owners] Aft cabin bigger bunk and Autoprop fouling

Steve Leeds

I'm sure his prop (and yours) is bronze and not brass or
steel. I used a relatively new New Zealand product called Prop-Speed
which is now sold in the US at my last haul over two years ago. At 22
months it was as good as new. I just completed a haul at 26 months and I
had a little growth on the leading edge. The product is very expensive
but obviously works. Very little is needed and it should be mixed in VERY
small mixing cups or it will be wasted. I have used the 250ml kit twice
and there is tons left. I noticed that there is a new smaller kit
available called a "sample" kit which would be more than enough for
several sailboat props. The kit includes a two part primer and a
silicon-like coating.

My boat has been lightly used the last two years. I suspect the product
will work well on a boat which is used more often but may not last as long.

John & Ann on Bali Hai,

Is your prop brass or steel. I have a Max, brass, prop on my

'82 Mango, "Windrush." Interested if the Aquiline Plus works on brass, what

does the direction on the can say?. I'm in the Chesapeake Bay with lots of

little ugly underwater friends.

We did a big job in order to get a bigger double bunk. There are some

pics in the Changes to Bali Hai album. It is great at at anchor

although Anne has to climb over my legs to get out before me. It is

alsso great when the boat is heeled as only one person will be using

it at a time and that person can lie fore and aft on the downhill

side.Construction details are given in msg #898.

I also know when the autoprop needs cleaning because even a small

amount of fouling will cause it to use too coarse a pitch and the

engine cannot reach full revs.If the fouling is bad the engine will

attempt to go faster and put out a lot of black smoke to foul the


We have connected a long hose to the regulator on the airbottle with

a scuba mouthpiece on the other end so that the bottle can stay on

deck midships whilst I clean the prop and or antifouling.

Normally cleaning the prop is necessary about three times a season

but this year I sanded it and gave it two coats of black propellor

antifouling called AqualinePlus from Jotun or Penguin Yachting. My

can was made in Italy by Orazio Brignola S.p.A but there is also an

address for Jotun Iberica S.A. in Barcelona.

The boat went in the water in May and I dived to clean the prop in

August clutching my wire brush,scraper and scourer. There were a

number of very small barnacles which were dead as they came off as

soon as I brushed them with my gardening gloves. I dived on the prop

again a couple of weeks ago and found virtually no fouling on it.

This was as I expected as the engine could still get up to 3100 revs

in flat water and no wind.

All the best, John, SM 319
